Ask a question


Sciatica is a term used to describe all pain symptoms relating to an irritation of the sciatic nerve. This type of pain can spread from the buttock to the foot. Sciatica can be chronic or reoccurring, and is responsible for pain resembling electric shocks in the areas innervated by the sciatic nerve. It is caused by pressure exerted on the sciatic nerve, notably in cases of disc herniation, by a tumor, or even a neurological disease. By administering analgesics, local corticosteroid injection, and physiotherapy, the pain symptoms can be relieved.
